Act as a web accessibility specialist. Audit {{page_or_component}} against WCAG 2.2 level AA. Here is the code or a detailed description: {{page_code_or_description}} Check headings and landmarks, accessible names for controls, keyboard access and focus order, visible focus, color contrast, text alternatives, form labels and error messages, motion and timing, zoom to 200 percent, reflow at 320px width, target size, announcements for content that updates, and the page language attribute. Return a table with columns: issue, WCAG success criterion, who is affected, severity, and the fix with corrected code. Then list the three changes with the biggest impact. Finish with what can't be confirmed from code alone and needs manual testing with a keyboard, a screen reader, or disabled users. Don't call the page compliant; a review like this can find issues but can't certify it.
